Collapsible microwave oven

Abstract

A collapsible microwave oven includes a main body, a cooking chamber defined within the main body, a magnetron for radiating high frequency microwaves to the cooking chamber, a high voltage transformer for applying high voltage to the magnetron, and an electronic component case containing the magnetron and the high voltage transformer. The electronic component case is mounted on the main body to be insertable into and withdrawable from the main body, whereby the space occupied by the oven can be reduced when the oven is not in use.

What is claimed is: 
     
       1. A collapsible microwave oven comprising: a main body;   a cooking chamber defined within the main body;   a magnetron for radiating high frequency microwaves to the cooking chamber;   a high voltage transformer for applying high voltage to the magnetron; and   an electronic component case containing the magnetron and the high voltage transformer, the electronic component case being mounted on the main body for movement relative thereto to be insertable into the main body and the cooking chamber when the oven is not in use, and withdrawable out of the cooking chamber and the main body when the oven is to be used.   
     
     
       2. The microwave oven of claim 1 wherein a rectangular opening is formed on a side of the main body through which the electronic component case is slidable, and a guide flange for guiding the insertion and withdrawal of the electronic component case is disposed around the rectangular opening, the guide flange extending from within the cooking chamber to the outside of the main body. 
     
     
       3. The microwave oven of claim 2 wherein the electrical component case includes an inner plate and a stopper flange disposed around the inner plate to control maximum withdrawal of the case, the stopper flange contacting a front end of the guide flange when the electronic component case is fully withdrawn. 
     
     
       4. The microwave oven of claim 3 wherein the electric component case further includes a rubber ferrite attached on the stopper flange to create a seal around the opening when the case is withdrawn, for preventing leakage of high frequency microwaves. 
     
     
       5. The microwave oven of claim 3 wherein a cover member is attached on an outer end of the electronic component case to enclose the guide member when the electronic component case is fully withdrawn. 
     
     
       6. The microwave oven of claim 5 wherein a roller is attached on a lower end of the cover member to aid the smooth movement of the electronic component case while supporting the case. 
     
     
       7. The microwave oven of claim 6 wherein a pull handle is attached on an outer surface of the cover member. 
     
     
       8. The microwave oven of claim 1 wherein a switch is disposed on a side plate of the cooking chamber for being contacted by a portion of the electric component case to supply electric power to the microwave oven when the electronic component case is fully withdrawn. 
     
     
       9. The microwave oven according to claim 8 wherein the main body includes an opening through which the case is slidable, when being inserted and withdrawn, the case including a rubber ferrite arranged to provide a seal around the opening when the case is withdrawn, the ferrite comprising the portion of the case which contacts the switch.
